Pro-Israel Republican donors are turning against Vice President JD Vance and shifting money to Marco Rubio for 2028, a bad sign for Vance's presidential hopes.

• Vance has criticized Netanyahu's government and backed a ceasefire with Iran, angering big pro-Israel donors who usually fund Republicans.
• Those donors are now signaling they will pour money into Rubio instead, who is positioning himself as the pro-Israel choice for 2028.
• Vance is trying to argue that criticizing Israel's government is not the same as hating Jews.
• Past incidents — his soft response to a leaked chat praising Hitler and a Turning Point event question — already made these donors uneasy.
• The 2028 GOP race is expected to be the most expensive in history, so losing major donors is a real threat.

Outlook: Expect Rubio to gain donor cash and momentum while Vance keeps fighting to hold his position in the pro-Israel wing of the party.
